Bought this after getting conflicting numbers from my IO hydrometer. This is easy to use and calibrate. I use it often as I'm starting a tank and have yet to even calibrate it. Takes a few seconds to measure and then a quick rinse w/ RODI and I'm done!

Very easy to use and calibrate and accurate results. Used to use a swing arm hydrometer but after I started investing in corals I wanted something I could trust a little more and for the price the BRS refractometer can not be beat! I have had it now for at least 8 months with no issues. The most it was ever off was .001 which was fixed with recalibrating with the including recalibration fluid

This is a great tool for the home aquarium. Was using a small needle type meter and found it was a solid 3 to 4 points off. Tested my tank with this little beauty and I was right at 1.026. Glad I didn't add more salt. This tool os so easy to use my wife is willing to check the salinity as it only takes a second.

Hydrometer was way offBy Anitaon 3/2/2013

I just received my refractometer and calibrated to the fluid. Tested my aquarium and about fell over! The salinity was reading 1.015! According to my swing-arm hydrometer, it was 1.023. I only have one coral -a very forgiving star polyp - and my fish have been fine. So I obviously need to bring that salinity up. That POS hydrometer is going in the garbage!

Well constructed and simple to use. Just make sure you calibrate with the provided solution - there is a large reminder sticker on the box. So far, appears to work exactly as intended.

I've been reefing for 4 years and always used a cheap plastic hydrometer. I haven't seen great growth in any livestock. Decided to dive into this refractometer. Glad I did. My plastic meter read 1.025. Tried the refractometer and it read 1.030! Made the adjustment and everything is thriving. A must purchase for little cost!

You can't beat the price and the accuracy of this refractometer. The calibration fluid that is included is an added bonus. The lines are large and easy to read.
